To 6.4 hemi owners
I was thinking about getting a '15 Ram with the 6.4 , but it states premium unleaded. The "14's used 87. It would not be worth to use premium over diesel for me. What is your opinion on this ?

Page 818 of the 2015 Ram owners manual states that they recommend 89 octane for 5.7L and 6.4L engines now.
